Data about the feeding ecology of the green toad (Bufotes viridis complex) from two hills near the city of Plovdiv, Mladezhki Hill and Bunardzhik Hill, are presented. The diet of the green toad consists mainly of insects, predominantly Hymenoptera (mostly Formicidae) and Coleoptera. When comparing the quantitative composition of the trophic spectrum between the two populations, we did not detect statistically significant differences. However, the value of the trophic niche breadth of the population from the Mladezhki Hill was significantly greater than that of the population from the Bunardzhik Hill, indicating that the first population feeds on more diverse prey. The overlapping of food niches between the two populations is low due to the different conditions and microhabitats of the two studied hills. The green toad can be classified as a polyphage (zoophage), which plays an important role in food chains, both in natural and urban ecosystems. [ABSTRACT FROM AUTHOR]

The weevil Larinus sibiricus Gyllenhal and a rich complex of associated hymenopteran parasitoids were reared from flower heads of Xeranthemum annuum L. (Asteraceae) in Bulgaria. As a result, the following taxa were established: Bracon urinator (Fabricius) (Braconidae), Exeristes roborator (Fabricius) (Ichneumonidae), Cyrtoptyx sp., Norbanus cerasiops (Masi), Pteromalus vibulenus (Walker), Stenoselma nigrum Delucchi (Pteromalidae), Exopristus trigonomerus (Masi) (Torymidae), Leptomastix ephyra Noyes & Hayat (Encyrtidae), Aprostocetus venustus (Gahan), Baryscapus sp. near carthami Graham (Eulophidae), Eupelmus microzonus Förster (Eupelmidae) and Eurytoma curculionum Mayr (Eurytomidae). Three of them (E. curculionum, L. ephyra and N. cerasiops) are recorded for the first time from Bulgaria and L. ephyra is a newly recorded species for the Balkan Peninsula and Europe. New associations with L. sibiricus and X. annuum were established for all reared parasitoids except B. urinator. [ABSTRACT FROM AUTHOR]

GECKOS ,REPTILES - Abstract
The seasonal and habitat variation of the trophic spectrum of Kotschy's gecko (Mediodactylus kotschyi rumelicus), as well as the species' trophic niche breadth was studied, based on feces analysis. The material was collected in spring and autumn of 2007 and 2008. The diet of M. kotschyi consists mainly of insects (59.51%), and from the non-insect food we registered Aranea (3.46%) and Acari (4.50%). From the insects, largest share have the ants - Hymenoptera, Formicidae (41.18%), followed by Coleoptera (11.77%), represented mainly by the Curculionidae family and Heteroptera (3.46%). In most of the samples (93.41%) were identified a significant amount of plant residues (32.52% of the total food). The taxonomic contents of the gecko's diet remains almost unchanged in the spring and in the autumn. The index of dominance of Berger-Parker (d) showed a moderate value of 0.41 and the trophic niche breadth, calculated with Simpson's diversity index (1/Simpson) was 3.53, which is relatively low value.

WOS: 000286013600004 This study was carried out to determine Eulophidae species, they have economical important for biological control, collected in various habitats in 2000 and between 2006-2008 in some provinces of Turkey. Specimens were collected with swepping net and reared materials especially on Agromyzidae leafminer species (Diptera: Agromyzidae). By identifying of the specimens, 23 species of 8 genera were determined in different localities. Of these species, 8 are new records for Turkish Eulophidae fauna. These species are: Dicladocerus westwoodi Westwood, 1832, Pnigalio nemati (Westwood, 1838), Chrysocharis pubens Delucchi, 1958, Neochrysocharis aratus (Walker, 1838), Pediobius brachycerus (Thomson, 1878), P. eubius (Walker, 1839), P. flaviscapus (Thomson, 1878), Sympiesis viridula (Thomson, 1878). With this study, the number of Turkish eulophid species were updated to 199 species that was previously 189 species.

Entedonomphale carbonaria (Erdös, 1954) (Figs 1–4) Thripoctenoides carbonarius Erdös 1954: 345 + fig. 12 c (p. 346). Type locality: Tompa, Hungary.

Thripoctenoides albicoxis Szelényi 1982: 387 –388. Type locality: Nagyiván, Hungary. Synonymized under E. carbonaria by Triapitsyn 2005: 285. New material examined. BULGARIA. Montana Region, Reservoir Ogosta (near Montana), 43 ° 23 ’09’’N 23 ° 12 ’ 53 ’’E, 175 m, 9.iv. 2005, A.K. Antonov (sweeping grasslands) [1 brachypterous female and 1 fully winged female, PUPB]. Distribution. Bulgaria, Canada, Germany, Hungary, Russia, Slovakia, Slovenia, Sweden, and USA (Triapitsyn 2005, Boyadzhiev & Triapitsyn 2007). Comments. As previously suspected by Triapitsyn (2005) and Boyadzhiev & Triapitsyn (2007), the female of E. kaulbarsi indeed turned out to be just a brachypterous form of E. carbonaria. The antennae and other morphological features are identical among E. kaulbarsi from Canada and the specimens of E. carbonaria from Bulgaria and Hungary, hence the synonymy. Coloration of the legs seems to be quite variable in this species: the legs of the brachypterous female from near Montana, Bulgaria, are pale brown while the legs of the fully winged female from the same location are mostly brown to dark brown. To assist with recognition of E. carbonaria, which has never been properly illustrated, we provide photographs of the antenna (Fig. 1) and the reduced fore- (Fig. 2) and hind (Fig. 3) wings of the brachypterous female, as well as the forewing and the hind wing (Fig. 4) of the macropterous female., Published as part of Triapitsyn, Serguei V., Boyadzhiev, Peter S. & Antonov, Anton K., 2008, Taxonomic notes on Entedonomphale (Hymenoptera: Eulophidae), pp. 61-64 in Zootaxa 1816 on page 61, DOI: 10.5281/zenodo.274368, {"references":["Erdos, J.

Entedonomphale postmarginalis (Shafee, Rizvi & Khan, 1988), comb. n. (Figs 5, 6) Euderomphale postmarginalis Shafee, Rizvi & Khan 1988: 2 (description, key [as E. Postmarginalis]), 3 (illustrations, figs D and E [as E. Postmarginalis]). Type locality: Bullandshahr, Uttar Pradesh, India. Entedonastichus postmarginalis (Shafee, Rizvi & Khan): Hayat et al. 2005: 10 (type information). Type material examined. Holotype female [ZDAMU] dissected on two slides, as follows. Slide 1 (head, one antenna, mesosoma and most of metasoma, and legs (with some segments missing) [under two coverslips]), labeled: 1. “Ref. No. 723 sp. n.”, 2. “ HOLOTYPE Euderomphale postmarginalis Shafee, Rizvi & Khan det. M. Hayat, 2003 ”; Slide 2 (one antenna, one forewing, and the ovipositor [under the same coverslip]), labeled: 1. “ 723 [in pencil] Ref. No 723 sp. n.”, 2. “ HOLOTYPE parts Euderomphale postmarginalis Shafee, Rizvi & Khan det. M. Hayat, 2003 ”. Diagnosis. Body and appendages mostly dark brown. Toruli slightly below lover ocular line. Antenna (Fig. 5) with scape (not counting a small radicle) 4.1 x as long as wide, a little dilated basally and medially. Pedicel longer than funicle; F 1 a little smaller than F 2, 1.1-1.5 x as wide as long, apparently without longitudinal sensilla; F 2 1.6 x as wide as long, at least with 1 longitudinal sensillum; clava entire, 1.6-1.7 x as long as wide. Mesosoma shorter than metasoma. Midlobe of mesoscutum with 1 pair of setae; anterior margin of scutellum slightly angulate. Forewing (Fig. 6) about 3.1 x as long as wide, with disc almost hyaline (with a slight brownish tinge throughout, perhaps a little more pronounced behind marginal and stigmal veins) and setose behind marginal and stigmal veins and beyond venation (more sparsely so behind base of marginal vein, and bare posterior of cubital row of setae); stigmal vein about as long as postmarginal vein; the longest marginal seta about 1 / 2 of maximal forewing width. Petiole longer than wide. Entedonomphale postmarginalis is undoubtedly a good species. In Triapitsyn (2005), E. postmarginalis would key to the couplets together with the species that have a hyaline forewing (i.e., E. boccaccioi S. Triapitsyn from the USA, E. bicolorata (Ishii) from Japan, Germany, and Ukraine, and E. esenini S. Triapitsyn from Madagascar). Entedonomphale postmarginalis differs from all of them by the female antenna, both funicle segments of which are wider than long (Fig. 5). Comments. This species was described (and is still known) from a single female holotype “ex aleyrodid on Citrus sp.” (Shafee et al. 1988). The host record seems doubtful and thus needs verification., Published as part of Triapitsyn, Serguei V., Boyadzhiev, Peter S. & Antonov, Anton K., 2008, Taxonomic notes on Entedonomphale (Hymenoptera: Eulophidae), pp. 61-64 in Zootaxa 1816 on pages 62-63, DOI: 10.5281/zenodo.274368, {"references":["Shafee, S.
